Chapter 1 Content Flashcards
What is charles law?
as temperature increases, volume increases with a constant pressure and number of moles and gas
What is the kinetic molecular theory?
as the gas particles have more energy, they move faster. In order for the pressure to remain constant, the volume must increase to accomodate an increase in collisions on the container
What is chemistry?
the study of matter, its properties, and the mechanisms involed in its changes
What are the properties of matter and their characteristics?
- Solids (defined shape and defined volume)
- Liquids (defined volume)
- Gases (undefined volume and shape)
- Plasma (gaseous state with lots of electrical charges)
What is an atom?

What is a molecule?
consists of 2 or more atoms connected by strong forces known as chemical bonds
What is matter composed of?
matter is composed of atoms, elements, and compounds
What are some physical properties?
size, color, shape, texture, melting and boiling point, dissolve
What are some chemical properties?
flammability (burn), acidity, oxidizing, and rust
